液晶显示装置的安装结构 技术领域
本发明涉及液晶显示领域， 尤其涉及一种液晶显示装置的安装结构。 背景技术
液晶显示装置 （ Liquid Crystal Display， LCD ) 具有机身薄、 省电、 无 辐射等众多优点， 得到了广泛的应用， 如： 移动电话、 个人数字助理 (PDA) 、 数字相机、 计算机屏幕或笔记本电脑屏幕等。
现有市场上的液晶显示装置大部分为背光型液晶显示装置， 其包括壳 体、 设于壳体内的液晶面板及设于壳体内的背光模组 （ Backlight module) 。 背光模组依照光源入射位置的不同分成侧入式背光模组与直下 式背光模组。 其中， 侧入式背光模组主要包括背板、 背光源、 反射片、 导 光板、 光学膜片组等， 其将背光源 LED灯条 （Light bar) 设于液晶面板侧 后方的背板边缘处， LED 灯条发出的光线从导光板 （Light Guide Plate, LGP) 一侧的入光面进入导光板， 经反射和扩散后从导光板出光面射出， 再经由光学膜片组， 以形成面光源提供给液晶面板。
随着液晶显示装置生产技术的不断发展， 液晶显示装置逐步趋向窄边 框化。 针对当前的具有侧入式背光模组的液晶显示装置， 由于窄边框化的 需要， 安装、 固定相关零部件的螺钉及螺紋长度越来越短。 请参阅图 1 至 图 3， 为一种现有的液晶显示装置的安装结构， 其包括： 背光模组 100、 设于背光模组 100 内的胶框 300、 设于胶框 300上的液晶显示面板 500及 设于液晶显示面板 500上的前框 700。
所述背光模组 100包括： 背板 110、 设于背板 110 内的导光板 130,安 装于所述背板 110上的背光源 150。
为縮小前框 700至导光板 130入光侧的距离， 所述背板 110兼具散热 板的功能， 其包括底板 111 及与位于底板 111 侧边的的第一侧板 113， 背 光源 150安装于第一侧板 113 内侧。 前框 700包括前板 720及及位于前板 720侧边的第二侧板 750。 所述第二侧板 750盖在所述第一侧板 113上。
所述前框 700的第二侧板 750上开设通孔 751， 所述背板 110的第一 侧板 113 对应所述通孔 751 开设螺紋孔 115， 一螺钉 900 穿过所述通孔 751 锁合于所述螺紋孔 115 内， 从而将所述前框 700 与所述背板 110 固 定、 安装在一起。 由于所述背板 110 —般由传热系数较高但硬度较低、 材^较软的铝或 铜等材料制成， 容易造成所述螺紋孔 115 与螺钉 900的螺牙结合不紧密， 连接强度不足， 产生滑牙现象， 影响所述前框 700与背板 110的固定、 安 装效果。 发明内容
